I'm getting tired of it.
Playing a thankless role is okay when just the act of doing it is enough. But once that enjoyment is gone, all that is left is the feeling that you're doing something for someone who could care less that you're doing it.
So couple the fact the person you are supporting could care less and the fact that you yourself could care less makes a light bulb appear over your head - "Why am I doing this?"
